Abstract
In this work, pellet type sorbents were prepared to control the low level indoor carbon dioxide withvarious physical compositions. In order to enhance the adsorption capacity, a few additives including alkalihydroxides were added to a commercial zeolitic sorbent by impregnation of alkali cation - Ca2+ throughphysical mixing and ion exchange. It was found that the binding materials such as dextrin or bentonitefacilitating to form the granular sorbents would assist the adsorption capacity of sorbents. The ion exchangewas more efficient for impregnation of alkalies, which showed better adsorption of gaseous CO2.
